I wanted to share the options we are considering for the primary and secondary tabs and get some feedback from the team. Here are the options and their strengths and weaknesses (that I foresee). Please feel free to add comments or respond to the thread on the list.
Entertaining different ideas for related tabs, to make the distinction between the primary tab and related tabs clear.
Showing the number of related records in the tab. It's a wealth of information at a glance and makes it clear that the tabs are for related records .
Showing "Current record" in the primary tab, and showing the procedure names in the secondary tabs. The tabs won't change record-to-record.
Displaying the record ID in the primary tab, and truncating the ID where necessary.
The following image illustrates the redundancy between the header and the primary tab.
